The CCU-100S is a Sony camera control unit which is typically part of a live television broadcast "chain."

It is responsible for powering the professional video camera, handling signals sent over the All in one camera cable (CB-49) to and from the camera and can be used to remotely control various camera parameters such as iris.

The system simultaneously transmits digital SDI and analogue signals as well as camera control, look back, camera view finder data, tally and intercom call signals between professional cameras and the switcher system.

CCU-100S and AD-2S form an integrated solution that allows you to get things done fast, easy and within budget.

Conferences, huddle rooms and presentations are fast paced environments where time is money and the audience does not like to wait. This is where an AV converter like the DAC-75T just thrives.
Your speaker wants to connect their laptop and see it displayed or projected straight away. They may have VGA, DVI, HDMI, Display Port or even SDI. So not getting the picture and fiddling with tiny dip switches, in a dark room, is what they want to avoid. Especially when there is no tech guy around.
